摘要: [6π+2π]-Cycloaddition of α,ω-diallenes and α,ω-bis(trimethylsilyl)diacetylenes to 1,3,5-cycloheptatriene in the presence a two-component catalytic system TiCl4-Et2AlCl was performed that led formation bis(endo-bicyclo[4.2.1]nona-2,4-dienes) bis(8-trimethylsilyl-endo-bicyclo[4.2.1]nona-2,4,7-trienes) linked by polymethylene spacer 69–86% yields.
